IMPROVED ROADSGRAPER.

Be-it known that I, NCHOLAS E. YOST, of Corry, in the county of Erie, and in the State of Pennsylvania, have invented certain new and useful Improvements in Machines for Scraping and Making Roads; and I do hereby declare that the following'is a full, clear,\and exact, description thereof, reference being had tothe acc'mpanying drawings, forming a partof this specication.

Figure 1 yis a plan View.

Figures 2 and 3 are vertical sections.

Figure 4 is n. detail 'showin-g extension-brace.

The nature of my inventi'on consists in the combination and arrangement of the mechanism hereinafter described, for the purpose of making an adjustable road-maker or scraper` Y A A' are two timbers, some sixteen feet long, twelve'inches wide, and four inches thick, and. faced on the outside edge and bottom with sheet iron, to makeit more durable.

B B' are two plough-points, secured by bolts or screws to the opposite ends of timber A. Apfew inches from thecdge of Ithesel points B are hinge-mortises a a, to receive the hinge-tongues b bof the castings C C',

which are securedby bolts or screws to the opposite ends of timber A'. The tongue of casting C may be inserted in the mortise of point B, and a bolt, c, be passed through them, thus hinging together the forward ends of'the two timbers A A'. f Y

At the centre, and on the inner faces of timbers AA', are bolted the castings D D', which are provided with hin'ge-mortises d d. l I v i An extension-brace, (formed oi" two pieces of tilmber, E E', made adjustable by means oi mortises e, tongues e', and boltf,) provided with cast tongues F E' at each end, which are secured by bolts in the mortises of castings D D', serve to brace firmly apart, at the desired angle, the two timbers A A'. l

Gr is a wooden or metallic box, secured to the upper inner edge of timber A', and is intended to be loadedwithstones, brick, Svc., to give weight to .the land-side lof the scraper.

H H' are two boards, eight or ten inches wide, and equal in length to the timbers A. The forward ends of these boards are secured together by the same bolt, passing through two staples, which secures the forward lends of timbers A A'. Other bblts, g h, g' 7L', passing through staples in these boards, secure them rmly to lthe timbers A A.

I is the tongue, having pivoted, about eighteen inches from the butt, the cross-bar J. The 'tongue J is secured to the scraper by bolt g, which secures board H to mould-board timber A. At the same time bolt c -passes through the cross-bar J, securing it firmly 'at the junction of timbers A A'. i i

K, the handle for guiding the mould-board.

The operatiouof my invention is as. follows:

My impro'ved road-maker is intended to be used for making,y scraping, or monding roads.

It is preferable to have-the road first brokenup by a plough. I

Suppose, now, I have a thirty-two-feet road, clear of ditches, to scrape or mend. I set my machine so that the outer width, at the rear, shall be sixteen feet, as shown in the drawings. The team is then. hitched, and the scraper' arranged so that the land-side A shall. just clear the edge 'ofthe ditch. The team is then started, and it draws along the scraperthc mould-board A' scraping and smoothing the road, and throwing up a furrow in the centre. When I come to a hollow in the road, I can raise the mould-board A', by means oi'- haudle K, and leave a little more soil at that point. When I have'gone the desired distance up the road, the scraper is turned around, and I come downjin-like manner, the landside now being next to the othei ditch, and the furrow being thrown to the centre, upon the other furrow. When I have thus gone up and down the road as often as is desirable, I change theattachment of thetongue froma. side draught to a direct draught. This is done simply by detaching the tongue,`as above described, and then fastening it simply by the bolt c, at the junction of timhers AA'. I then drawthe scraper'right up the centre of the road, equally dividing and distributing the furrow tothe right and iefti I A In making or niending those roads where it is inconvenient or impossible to turn the scraper entirely around, I first detach the tongue and'team, after going up the road. then remove bolt c, and simply bring together the 'other ends of timbers A A' and; boards H H', and secure them together, andalso the tongue I, by means of bolt c, as before described.v The scraper is then drawn down the road, the land-sidc retracing the same track it made=in going up. I Y l I f The extension-brace E 'E' enables me to easily contract or expand my scraper to suit the iridth'ofthe road to be operated upon.

Experience has shown that roads can be mended much cheaper and better by my improved scraper thanA by any other known means. l

Having fully described my invention, what I claim as ncvnand desire to secure by Letters Patent, is

1. The reversible timbers A A', pivoted upon a centre brace, when constructed and operating substantially as and for the purposes set forth.

2. Thev timber A, in combination with the two plough-points, B B', constructed and operating substantially= as and for the purposes set forth. i l A,

V3. The timber A', in combination with the two castings C C', constructed' and operating substantially as and for the purposes set forth. l

4. The extension-brace E E', in combination with mortise e, tonguesf, bolt g, and castings D D", constructed and operating substantially as and for the' purposesv set for-th., I l

5. The tongue I-and cross-bar J', when secured to the scraper by means of bolts c'and* ,and in combination with the timbers A A', constructed and operating substantially as and for the purposes set forth.

In testimony that I claim the above-described invention, I havehereunto signed my name, this 15tlrday of February, 1868. l
